IMPROVEMENT IN LAMP-EXTINGUISHERS.

Specification forming part of Letters Patent N o. 170,064,

dated November 16, 1875; application filed March 16, 1875.

To all whom it may concern.-

Be it known that I, WILLIAM C. GROSS, of Boston, in the county ofSuffolk and State of Massachusetts, have invented certain Ilnpiovementsin Lamp-Extinguishers; and I hereby declare the following to be a full,clear, and exact description thereof, reference being had totheaccompanying drawings making part of this specification, in {which-vFigure l is a perspective o 'the extinguisher as attached to a wicktube.Fig. 2 is a vertical cross-section with thewick raised. Fig. 3 is` avertical cross-section with the Wick down.

rEhe object of my invention is to provide a cheap lamp-extinguisher thatwill not foul or allow dirt to enter the wick-tube; `and it consists intwo plates which are pivoted at the top and out of line with thewick-tube, and are operated by springs, as hereinafter set forth.

In the said drawings, A is the wick-tube of a lamp-burner. On the outersurfaces of the"t upper edges of the tube I pivot, by rivets c a, twoplates, B B, shaped substantially as sh`own, and having flaring ilangesbb, under which bearsprings c c, having their ends soldered to the baseof the burner. Each ofthe plates B O has one of its sides turned atright angles above the pivots, so that they form at their tops arectangular holding-surface for the wick. The plates together form ahood, which at its baise is larger than the wick-tube.

When the wicl:V is forced up it represses the springs ari'd forces theplates apart, as seen in Fig. 2. The opening between the end of thelamp-wick tube and the bases of the plates allows the air to circulatearound the tip of the tube and almost to the burning-point of the wick,thus keeping the wick-tube or oil from heating. y

` When the Wick is drawn down the plates assume the position seen inFig. 3, and the opening at the base of the plates so enlargesv as tofreely allow any dirt or charred Wick which may have accumulated aroundthe top of the plates tofescape, and none Vwhatever goes into thewick-tube to clog the gearwheels.

lThe lsprings c c are soldered in such a way as to protect them as faras possible from any heat from the llame.

The scraping action or effect of the upper edges of the plates B B uponthe tip of the wick is'such as to keep it cleared of'charred or gummymatter. r

Having thus describedmy invention, what I claim as new, and desire tosecure by Letters Patent, is

The plates B B, arran ed to have openings between their basesan thewick-tube, in combination with the sprin gs c c and wicktube A,substantially as described.
